Rotary Hammers

Rotary hammers have been around for years and have only improved over time. The most common use for rotary hammers is drilling into concrete, or something as hard as concrete. The rotary hammer looks like a huge drill and it is considered to be in the category of that tool. However, it is called a hammer because it moves the rotary bit in and out at a rapid speed in order to break up the concrete while drilling through it.
